Application filed December 6, 1913.

To all whom it may concern:

Be it known that I, TI-IoMAs F. MARTIN,

citizen of the United States, residing at Sabra-ton, in the county of Monongalia and State of West Virginia, have invented certain new and useful Improvements in Guards for Pets or Crucibles, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to screens and more particularly to an improved guard screen, the invention having for its primary object to provide a device of this character adapted to be arranged contiguous to a metal pot or crucible whereby all liability of the workmen or puddlers stepping into the molten metal and thereby sustaining injury will beobviated.

The invention has for another and more specific object to provide a device which is very simple and effective in use, the same consisting of a main bar mounted upon a supporting plate secured to the wall of the pot, said bar being provided with a pinrality of openings therein, a series of screens having hooks adapted to be loosely fitted in the openings of said bar, and an additional screen loosely connected to said first named screen.

A further object of the invention is to produce a device of the above character which may be easily and quickly arranged in position for use or removed from the pot, and is capable of manufacture at comparatively small cost.

With the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a top plan view showing my improved guard screen applied to a metal pot; Fig. 2 is a side elevation showing the several screens elevated and supported against the grease pot of the metal containing pot. Fig. 3 is a section taken on the line 33 of Fig. 1.

Referring in detail to the accompanying drawing, 5 designates a metal receiving pot which is provided with the usual flux box 6, and at one end of which the grease pot 7 is Specification of Letters Patent.

located. This metal receiving pot is of the usual approved form now in general use and further description thereof is therefore considered unnecessary.

Upon the metal pot 5 adjacent the upper edge thereof, a horizontally disposed plate 8 is secured. This plate is of a general U shaped form and upon the same adjacent its ends, upstanding pins 9 are secured. These pins may be threaded, cemented or other wise fixed in the supporting plate.

10 designates a rectangular metal bar which is provided in its ends with openings 11 to receive the pins 9. Additional openings 12 are also provided in the ends of this bar and at spaced points the elongated slots 13 are formed. A'pair of guard members 14: are adapted to extend from the metal bar 10 to the longitudinal bar of the supporting plate 8 upon which the free ends of the screen or guard members are supported. The screens may be constructed of reticulated or imperforate material as de sired, and provided with a suitable boundary frame or reinforcement around its edges which terminates at its ends in the hooks 15. Qne of the hooks upon each of said guard members is adapted to be loosely fitted into one of the openings 12 of the bar 10 while the other hook 15 is engaged in one of the elongated openings 13 in said bar. 16 designates a central screen or guard member which is also provided with hooks 16 for engagement in the respective openings 13 of the bar 10. The end rods of this latter screen upon which the hooks 16 are formed are provided upon their opposite ends with the eyes 17, to receive the hooks 19 on a supplementary screen 18. This latter screen is movable with relation to the screen 16 and is adapted to extend over the flux box as clearly shown in Fig. 1.

From the above description it is believed that the construction and manner of use of my invention will be clearly and fully understood. The several screens or guard members are normally disposed horizontally and extend forwardly from the bar 10 over the open top of the pot 5 and rest at their free ends upon the supporting plate 8. Thus puddlers or workmen moving between a large number of pots are protected against liability of making a misstep and placing the foot in the molten metal. When it is desired to skim the dross from the surface of the metal, the screen 18 is laid back upon several parts employed, it is to be under the screen 16. This latter screen as well as the end screens 14 may be elevated, the hooks of said screens rotating freely in the openings in the bar 10. Said screens are then supported in a leaning or inclined posi- 1131011 by the grease pot, 7 as clearly shown in lfiy the use of my improved guard device above described, the possibility of serious injury to the workmen is effectually over-f come; 1 I v 7 :It will be obvious that the screens can be removed by simply lifting the bar 10 from the pins-9, or if desired, the several guard Itstood that the invention is susceptible of 1 considerable lmodification therein. and I therefore reserve the right to-resort to all such legitimate modifications as Ina-y.-be

' fairly embodied within the spirit' and scope of the invention, asxclaimed.

Having thus described the invention, what is claimed is:

1, The combination with a metal receiving 7 pot or the like, sofa supporting plate-secured to the pot and provided with upstanding pins, a bar having openings in its opposite ends to loosely receive-said pins, additional openings in the bar, a plurality of screens movably mounted at one of their ends upon the bar and adapted, when in their operative positions to extend overthe open top of the'pot and rest at their free ends upon said supporting plate.

2. The combination with ametal receiving 7 pot or the like, of a supporting plate secured upon said pot, a barremovabl'y mounted' upon said plate and :provided with a plurality of openings, a series of screenshavlng hooksloosely engaged in said openlngs, and asupplementary' screen movably connected to one ofthe first: named'screens,

said latter screen .and'the other first named open top of the pot,-said screensbeing detachable from the bar and movable with respect thereto to permit of access to the pot. I

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
